Resample is a small command-line application for converting sample rates and playing back audio data. It is based on a 16 bit fixed-point MMX-optimized polyphase filter bank, and should run in real time on any almost any processor. It is processor independent but requires the Linux Open Sound System to run.
Increase or decrease of the number of pixels in one or both axes of an image using a method that correlates adjacent pixel values to create a smooth pixel-to-pixel brightness transition.
The changing of the pixel dimensions (and therefore physical file size) of a picture or a graphic. Graphics can be resampled down (the number of pixels is decreased) or resampled up (the number of pixels is increased). When you resample a graphic down, pixel information is deleted from the graphic. When you resample a graphic up, new pixel information is created based on matching color values of the existing pixels. Resampling a graphic down and then resampling it up to its original resolution will cause the quality of the graphic to deteriorate considerably. In FrontPage, the Pictures toolbar contains the Resample command.
Changing the pixel dimensions of a bitmap image. When you decrease the number of pixels in the image, you are downsampling, which results in a loss of image data and a blurrier image. Use downsampling to reduce the file size and viewing dimensions of an image for web or e-mail publishing. When you increase the number of pixels in the image, you are upsampling. Upsampling also often results in a blurry, pixelated image. You should avoid resampling images that are going to be printed.
To change the resolution of an image. Resampling down discards pixel information in an image; resampling up adds pixel information through interpolation.
To change the size and resolution of a bitmap.
To interpolate cell values in a raster object and create a raster with larger or smaller cells.
To recalculate Sample in a sound file at a different Sample Rate than the file was originally recorded. If a sample is resampled at a lower rate, sample values are removed from the sound file, decreasing its size, but also decreasing its available frequency range and possibly introducing Aliasing. Resampling to a higher sample rate, often interpolates extra sample values into the sound file. This increases the size of the sound file but may not increase the quality (depends on the algorithm used).
Change an image's resolution while keeping its pixel count constant.
( Bootstrap, Permutation Procedures, Random Sampling) is an artificial data set constructed from a given collection of real data [pg. 145, 3
Change sample pitch to make it sound like other note while preserving original sample rate. Resampled samples last longer or shorter than original sample. Resampler has limited range of operations - depending on quality of resampling function. In Renoise, we use highest quality resampling functions (cubic and sinc) to maximize this range.
